F E A T U R E S T O RY 3 9 TUNNELINGONLINE.COM TBM: TUNNEL BUSINESS MAGAZINE // JUNE 2018 In addition to making the recommenda- tions clearer, i.e. in terms the project man- ager is familiar with, the geotechnical en- gineer should collect supporting data from additional sources such as sampling and analyzing rocks from the stockpile and/or reviewing probe drill data and use these to build a convincing argument. In the modern highly mechanized world otechnical engi- neer has access to many methods of collect- ing raw data from dozens sources both on ound the site. The geotech- nical engineer needs to translate the data into knowledge and wisdom and share that with the project manager. Data and infor- mation, while critical to the geotechnical engineer, is useless to the project manager and will only confuse the issue if not pre- sented in a clear and concise manner. CONCLUSION oject no matter how much time and money is spent up front will ever have all of the information. By getting good geo- technical advice early in the project and then continuing to work with the geo- technical engine election and design, the project manager will more likely to be able to succeed. An experienced project manager un- derstands that the competence and expe- rience of the geotechnical engineer can make the difference between meeting the project goals or incurring delays and additional costs. The ability of these two people to understand each other and work together during the construction of the tunnel is critical. The geotechnical engineer must try to understand the pressures that the project manager is under the conflicting priorities that he must resolve daily. Deliver knowl- edge and share wisdom and becoming an ally rather than just another source of conflict that has to be resolved. REFERENCES 1.
